A frequent AC repair issue is a system that’s blowing warm air. This makes the device effectively useless, and the problem could have several causes. Here are some of the most common reasons your AC unit isn’t putting out cold air. 

Why Is Your AC Blowing Warm Air?

1. Refrigerant Leak

Air conditioners transport indoor heat outdoors using refrigerant. This is a fluid with a low boiling point, so it evaporates easily. Evaporation absorbs heat from a surface whenever a liquid changes into a gas.

The gas—and the absorbed heat—are pumped to the outside unit (or condenser), where the fluid condenses into liquid again and releases the stored heat. If the system has a refrigerant leak, this heat transfer can’t take place, and the AC unit will blow warm air.

2. Bad Compressor

The compressor is the pump that keeps the refrigerant flowing. If the compressor fails, the refrigerant won't move, heat transfer won't take place, and the system won't blow cool air. A bad compressor requires significant AC repair, so you'll need to call an experienced HVAC contractor for help.

3. Clogged Condenser Coils

To work efficiently, the AC system needs to vent the hot air it collects. If the condenser coil of the outdoor unit is clogged with dirt, leaves, grass, or other debris—or if the vents are blocked by boxes, lawn furniture, or other items—the stored heat can’t be released, and the system will blow warm air. Before calling a professional, make sure the condenser coil isn't clogged with debris and heat can vent effectively.
